Two examples of pleated filter media are shown at left. The brown one (1) is cellulose based. It is made of paper. The white one (2) is made of synthetic material, which generally lasts much longer than cellulose.
In the bottom left photo (3), the Case filter shows a bypass mechanism on top of the filter media. If the main filter media becomes clogged, the bypass mechanism will filter the fluids, as a back up. This type of system provides additional protection against filter failure.
